tParAccelCommit – Docs for ESB 7.x


Commits in one go a global transaction, using a unique connection, instead of doing
that on every row or every batch and thus provides gain in performance.

The tParAccelCommit validates the
data processed through the job into the connected DB.

tParAccelCommit Standard properties

These properties are used to configure tParAccelCommit running in the Standard Job framework.

The Standard
tParAccelCommit component belongs to the Databases family.

The component in this framework is available in all Talend

Note: This component is a specific version of a dynamic database
connector. The properties related to database settings vary depending on your database
type selection. For more information about dynamic database connectors, see Dynamic database components.

Basic settings


Select a type of database from the list and click

Component list

Select the tParAccelConnection
component in the list if more than one connection are planned for
the current job.

Close Connection

This check box is selected by default. It allows you to close the
database connection once the commit is done. Clear this check box to
continue to use the selected connection once the component has
performed its task.


If you want to use a Row

connection to link tParAccelCommit to your Job, your data will
be committed row by row. In this case, do not select the
Close connection check
box or your connection will be closed before the end of your
first row commit.

Advanced settings


Select this check box to collect log data at the component


Usage rule

This component is more commonly used with other tParAccel*
components, especially with the tParAccelConnection and tParAccelRollback components.

Dynamic settings

Click the [+] button to add a row in the table
and fill the Code field with a context
variable to choose your database connection dynamically from multiple
connections planned in your Job. This feature is useful when you need to
access database tables having the same data structure but in different
databases, especially when you are working in an environment where you
cannot change your Job settings, for example, when your Job has to be
deployed and executed independent of Talend Studio.

Once a dynamic parameter is defined, the Component List box in the Basic
view becomes unusable.

For examples on using dynamic parameters, see Reading data from databases through context-based dynamic connections and Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic
and context variables, see Talend Studio
User Guide.
